Clustering for point data layer

Clustering for point data layer

Hello,

do you support clustering for points? I want to see a number of items, which stay on the same point (in near of). Or I like to see other images/icons for this case, so that I can see, at this point exists two or more data.

I see something like this here: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#SimpleClusterer
